FIELD

The present invention generally relates to portable computing devices,and more particularly, to portable computing device docking stations.

DESCRIPTION OF THE RELATED ART

Portable computing devices (PCDs) are ubiquitous. These devices mayinclude cellular telephones, portable digital assistants (PDAs),portable game consoles, palmtop computers, and other portable electronicdevices. As technology increases, PCDs are becoming increasinglypowerful and rival laptop computers and desktop computers in computingpower and storage capabilities.

One drawback to using a PCD, however, is the small form factor typicallyassociated therewith. As the PCD gets smaller and is made more easilyportable, using the PCD may become increasingly difficult. Further, thesmall form factor of a PCD may limit the amount of ports, orconnections, that may be incorporated in the shell, or housing, of thePCD. As such, even as PCDs become more powerful and have increasedcapabilities, access to the power and capabilities may be limited by thesizes of the PCDs.

Accordingly, what is needed is an improved for system and method fortaking advantage of the computing capabilities provided by a PCD.

Otherwise, if the PCD docking station battery power isequal to the critical condition, the method 3300 may proceed to block3324 and the power management module may transmit a second warning tothe user. The second warning may be an audio warning, a visual warning,or a combination thereof.

From block 3324, the method may continue to decision 3326 and the powermanagement module may determine whether a power source is plugged intothe PCD docking station. The power source may be an alternating current(A/C) power source, an external direct current (D/C) power source, or acombination thereof. If a power source is plugged into the PCD dockingstation, the method 3300 may continue to block 3328 and the powermanagement module may charge the PCD docking station battery from thepower source. Thereafter, the method may return to block 3305 of FIG. 33and continue as described herein.

Returning to decision 3326, if the power management module does notdetect that a power source is plugged into the PCD docking station, themethod 3300 may proceed to block 3330 and the power management modulemay switch the power supply to the PCD and the PCD docking station fromthe PCD docking station battery to the PCD battery. Next, at block 3332,the PCD docking station and the PCD may be powered from the PCD battery.

Moving to block 3334, the power management module may monitor the PCDbattery power. At decision 3336, the power management module maydetermine whether the PCD battery power is equal to a power downcondition. For example, the power management module may determinewhether a remaining battery power associated with the PCD battery isbelow a predetermined value, e.g., a percentage (%) of total PCD batterylife. If the PCD battery power is not equal to the power down condition,the method 3300 may return to block 3334 and continue as describedherein. Conversely, if the PCD battery power is equal to the power downcondition, the method 3300 may continue to block 3338 and the powermanagement module may turn off the PCD/PCD docking station combinationmodule. Then, the method 3300 may end.

With the configuration described herein, the PCD/PCD docking stationcombination provides feature segmentation between the PCD and the PCDdocking station. A PCD may be engaged with a PCD docking station in oneof the manners described herein. For example, a PCD may be engaged witha PCD engagement mechanism, e.g., a PCD docking pocket, a PCD dockingtray, or a similar mechanism. Further, dual display usage is provided,e.g., by a display in a PCD and a display in a PCD docking station. Whenengaged with a PCD docking station, a PCD may be charged by the PCDdocking station. Moreover, seamless user interface and applicationtransition may be provided as the PCD is docked or undocked.

In a particular aspect, user interface features may be provided when aPCD is docked or undocked. One such aspect, is a “fish-eye” bubble thatmay be provided across all applications displayed on the PCD.Additionally, application layer scaling may be provided. For example, aprimary application version may be executed when a PCD is docked and asecondary application version may be executed when a PCD is undocked.Alternatively, a standard application version may be executed when a PCDis undocked and an enhanced application version may be executed when aPCD is docked. In an undocked mode, a PCD may execute less computationalintensive, smaller footprint applications. In a docked mode, fullfunctionality applications may be executed by the PCD. Whether a PCD isdocked or undocked may be automatically detected and the appropriateapplication versions may be executed when available.

When a PCD is undocked, two low power processors may be used for smallscreen applications and the PCD operating system (OS). Further, two highperformance processors may be used to execute larger applications whenthe PCD is docked with a PCD docking station. In another aspect, whenthe PCD is docked, one processor may be used for mouse controls andgraphical user interface controls, i.e., touch screen controls; oneprocessor may be used for shared input/output controls; one processor beused for a PCD OS; and one processor may be used for a desktop OS storedon a PCD docking station. In yet another aspect, each processor may runa different OS and framework.

A PCD docking station may be connected to a home network and when a PCDis docked with the PCD docking station, the PCD may, in turn, beconnected to the home network. Moreover, data, e.g., applications,content, or a combination thereof, may be automatically backed up to aPCD docking station when a PCD is docked with the PCD docking station. APCD docking station may include a display, a display buffer, a HDD,additional memory, LAN capabilities, WLAN capabilities, one or more USBports, printer connections, a keyboard, a mouse, etc. The PCD dockingstation may include a large screen application memory. A large screenapplication and an OS state may be retained in the PCD docking stationmemory when the PCD is undocked in order to enable instant-on when thePCD is again docked. A large screen application may include a browserapplication, a word processor application, a spreadsheet application, apresentation application, an email application, a calendar application,a video application, or a combination thereof. A small screenapplication may include a media player application, a phone application,a control application, or a combination thereof.

When a PCD is docked with a PCD docking station, a user can takeadvantage of a relatively larger display incorporated into the PCDdocking station. Further, a user may use a full keyboard and mouse toaccess data stored in the PCD. A PCD docking station may be incorporatedinto a vehicle, a kiosk, a set top box, etc. and a PCD may be dockedtherewith.

It is to be understood that the method steps described herein need notnecessarily be performed in the order as described. Further, words suchas “thereafter,” “then,” “next,” etc. are not intended to limit theorder of the steps. These words are simply used to guide the readerthrough the description of the method steps.

In one or more exemplary aspects, the functions described may beimplemented in hardware, software, firmware, or any combination thereof.If implemented in software, the functions may be stored on ortransmitted over as one or more instructions or code on acomputer-readable medium. Computer-readable media includes both computerstorage media and communication media including any medium thatfacilitates transfer of a computer program from one place to another.
